C Programming for Arduino

By: Julien Bayle

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

What does digital mean?

Let's define precisely what the digital term means here.

Digital and analog concepts

Digital, in the computer and electronic worlds, means discrete, which is the opposite of analog/continuous. It is also a mathematical definition. We often talk about domains to define the cases for use of digital and analog.

Usually, the analog domain is the domain related to physical measures. Our temperature can have all the values that are possible and that exist, even if our measuring equipment dosen't have an infinite resolution.

The digital domain is the one of computers. Because of the encoding and finite memory size, computers translates analog/continuous values into digital representations.

On a graph, this could be visualized as follows:

Inputs and outputs of Arduino

Arduino owns inputs and outputs. We can also distinguish analog and digital pins.

You have to remember the following points:

  • Arduino provides digital pins that can be both an input or an output

  • Arduino provides only analog...
